Description: Sonic Sky Chase is a very basic online game that relies on Sonic the Hedgehog's ability to transform into a blue ball and destroy the evil airplanes that keep flooding the screen. Sonic is riding on top of an airplane which you can control by pressing the arrow keys. When you see an airplane coming your way, just go right in front and under it and press the space bar. This will turn Sonic into a ball that jumps in the air and will destroy the airplane. Each level you pass you will notice the increase in difficulty.
